**Ben Bernanke has been approved to serve a second four-year term as chairman of the US Federal Reserve.**The US Senate voted 70-30 in favour of Mr Bernanke serving a second term at the US central bank.
Mr Bernanke had faced the stiffest opposition to any nominee for Fed chairman in the three decades that the Senate has voted on the position.
Mr Bernanke has been criticised by some for not doing enough to prevent the economic crisis.
His nomination had earlier cleared a procedural hurdle with a 77-23 vote.
Mr Bernanke replaced Alan Greenspan as chairman in 2006.
